Question

Продавщица разрезала ткань на два отреза в первом отрезе было 7 метров во втором 15. второй отрез стоил на 400 р дороже первого отреза.какова стоимость всей ткани.

Answer 1

15-7=8 м 
8м = 400р 
400 разделить на 8 получится 50 р 
15+7=22
22 умножить на 50 =1100
ответ 1100 рублей стоила ткань

Answer 3

Calculation of the Total Cost of the Fabric

To calculate the total cost of the fabric, we need to determine the cost per meter for each piece and then multiply it by the length of each piece.

Let's assume that the cost per meter of the first piece is x rubles. Since the second piece is 400 rubles more expensive than the first piece, the cost per meter of the second piece would be x + 400 rubles.

The length of the first piece is given as 7 meters, and the length of the second piece is given as 15 meters.

To find the total cost of the fabric, we can use the following equation:

Total Cost = (Cost per meter of the first piece * Length of the first piece) + (Cost per meter of the second piece * Length of the second piece)

Let's substitute the values into the equation:

Total Cost = (x * 7) + ((x + 400) * 15)

To solve for the total cost, we need to find the value of x. Unfortunately, the provided information does not give us enough information to determine the value of x. We would need additional information, such as the total cost of the second piece or the total cost of both pieces combined.

Without this additional information, we cannot calculate the total cost of the fabric.
